SIDING OR CLAPBOAR D MARKER.

SPECIFICATION forming part of Letters Patent No. 412,594, dated October 8, 1889.

Application filed April 29, 1889- Serial No. 309,016. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN T. BRODEN, a subject of the King of Sweden and Norway, and a resident of Sioux City, in the county of Woodbury and State of Iowa, have invented. certain new and useful Improvements in Siding or Clapboard Markers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a perspective view. Fig. 2 is a section taken where the broken line w w is marked on Fig. 3. Fig. 3

shows the marker with the cover removed.

and a portion broken away. Fig.4 is an end view.

This invention relates to markers to be used in fitting siding or clapboards to houses; and

it consists in the construction and novel com-v board to the required length to accurately fit in position.

In the accompanying drawings, the letter A designates a narrow rectangular metallic box or frame of suitable length, having a slotted bottom B and cover 0.

B is a metallic strip firmly secured to the bottom B of the box, and extended at each end thereof to form projections 01. a for the attachment of supporting-arms b b, which extend forward a suitable distance at right angles to the length of the box-frame to embrace between them the edges of the sidingboard to hold the same in position when marking. The under surfaces of the arms I) b are rabbeted, and through apertures rivets are passed, securing the arms respectively to the ends a of the strip B.

rights 6.

Between the bottom of the box and the under surface of the arms I) b and the strip B is an intervening way or guide-slot for the reception of the marking-knife D. This marking-knife D is of elongated rectangular shape, and is serrated on its forward edge e to mark the'board as a guide for sawing, and is provided with a handle or grip E at the back. The upper side of the knife is provided with upright lugs or posts 6 e, situated near each end thereof, which project through slots h h in the bottom B of the box. Each post 6 serves as a point of attachment inside the box for one end of a spiral spring 11, the opposite end of each spring being secured to a hook or loop k on the inside wall of the box. A semi-elliptic spring- J is clipped inside the box opposite the spiral springs t 1 and its free ends respectively bear under and against the up- The object of the spring attachments is to steady the marking-knife to hold it in withdrawn position and regulate its action when in use. The marking-knife is contrally slotted at z for the passage of the middle securing-screw V, which holds the outer guide-plate B to the bottom of the box. The motion of the knife given by means of its handle H is limited by the area of the slots h h and the lugs e e, which operate in said slots.

When in practical use, the board-marker is applied and operated as follows: A clapboard, having been secured temporarily at one corner of the house in course of construction, is held against the corner or facing strip in the required horizontal position by means of the arms I) b of the marker between which the board is placed. The outer fiat sides of the arms are then made to bear against the inner or meeting edge of the corner-strip, and the face of the box between the arms 17 b bears against the board to be marked, and thus brings the marking-knife in line with the perpendicular meeting edge of the corner-strip. The marking-knife is then thrust forward against the board by means of the handle, and is given a vertical or up-and-down motion, which scratches the face of the board, forming a cross-marking at the front, where it is designed to be sawed. The board is then re moved to the carpenters bench, the super springs connecting at their outer ends to said studs and having their inner ends connected about centrally to said closure, and the semielliptic spring centrally secured 'to said closure and bearing near its ends upon said studs, securing the marking-blade in a withdrawn position, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
